In a tug of war contest, two groups of people pull on a horizontal rope from the two ends. The winning group will be one which-

(a) exerts greater force on the rope

(b) exerts a force on the rope which is greater than the tension in it

(c) exerts greater force o the ground

(d) makes a greater angle with the horizontal

the answer is (c).........

the group which exert greater force on the groung will win ....

this is coz when they apply greater force on the ground then ground will also apply greater reaction thus team wins...

this can be compared to the condition when a horse applies a force on ground to move in foreward direction....

greater the force applied by horse , greater will be reaction of surface & hence greater will be accleration....

the winning team will be that which will apply a greater force on the rope
